Monitor NCCL Benchmark Runs with Prometheus and Grafana

💡 Quick Answer: Combine NCCL benchmark logs with GPU metrics (utilization, memory, interconnect indicators) in Grafana dashboards to detect performance drift across cluster changes.

Benchmark snapshots are useful, but trend-based monitoring catches regressions sooner.

Data Sources

• NCCL benchmark output logs
• DCGM exporter metrics
• Node and pod metadata labels

Dashboard Suggestions

• Benchmark run duration by node pair
• Effective bandwidth trend by test profile
• GPU utilization and memory during tests
• Failure count per benchmark type

Operational Practice

Schedule recurring benchmark jobs and alert when bandwidth drops below baseline thresholds.
